I've lost XFS and JFS filesystems in the past due to their failure to |
| 8 |
recover after sudden power loss. Ext3/4 have not failed me (yet). |

But my question is, why don't you use a UPS and monitoring software to |
| 11 |
perform a proper (clean) shutdown when power's off and battery is |
| 12 |
running low. Some UPS also support automatic power-on once things are |
| 13 |
normal again, in case this is an unattended box that locals can't be |
| 14 |
bothered with rebooting themselves. |

I can think of making a complicated system with read-only boot media |
| 17 |
(cd/dvd/mmc/whatever) which attempts recovery of important data (logs |
| 18 |
created since last backup) to a spare partition, RAM drive or the |
| 19 |
Internet, then repartitions & reinstalls itself to the harddrive and |
| 20 |
restores the recovered data. Optionally downloading updated configs |
| 21 |
from Internet. (think kiosk distros). |
